The sanitary sewer overflow reported by the Baltimore City Department of Public Works in the early evening of April 8, 2015, was stopped later that night. The estimated flow was 100 gallons per minute, resulting in a 23,000-gallon release into Armistead Run, a tributary of Herring Run, near Federal Street in East Baltimore.

The cause of the overflow was attributed to a 24-inch broken pipe.
The stream has been posted and cleanup operations have begun. The Maryland Department of the Environment and the Baltimore City Health Department have been notified. For more information about health concerns as a result of sewer overflows, contact the Health Department at 410-396-4422.
